Description

Technical Field

[0001] The utility model relates to the technical field of detection control devices, in particular to a detection control device for multiple metal contents in urban sludge. Background Art

[0002] The physical and chemical properties of municipal sludge are determined by the nature of sewage and the treatment process. After mechanical dehydration, the water content of sludge is generally about 80%. Since my country mostly uses the combined treatment of urban domestic sewage and industrial wastewater, the sludge composition is complex and the content of some heavy metal elements is high. At present, when testing the multiple metal content of municipal sludge, it is necessary to sample the municipal sludge and bring the municipal sludge sample back to the laboratory for multiple metal content testing;

[0003] For example, the utility model with patent publication number CN212722859U discloses a device for detecting and controlling the multiple metal contents in urban sludge. Through the coordinated arrangement of a sludge pump, a sludge extraction pipe, a sludge delivery pipe and a mixer, the extracted sludge can be sent to the inside of the mixer for uniform mixing during use. With the arrangement of a discharge pipe, a control valve, a transition bin and a distribution pipe, the mixed sludge can be evenly distributed, thereby achieving a better uniformity of the sludge sample. Through the arrangement of a heavy metal detector, the device for detecting and controlling the multiple metal contents in urban sludge has the effect of detecting the content of heavy metals in sludge. Through the coordinated setting of the test tube rack and the cleaning box, the detection end of the heavy metal detector can be cleaned before detection during use. Although it is convenient for detecting multiple metal contents in urban sludge, it is necessary to manually clean the detection end of the heavy metal detector during detection, and then detect the urban sludge sample in a test tube. After the detection is completed, the detection end of the heavy metal detector needs to be cleaned again. To detect multiple sludge samples, the above actions need to be repeated many times.
